Write a program to Multiply three numbers using arithmetic operators in java

Hello guys, welcome to lingarajtechhub.com . Today we are going to discuss multiply three numbers using arithmetic operators in java.

Code:

package com.multiplication.java;

import java.util.Scanner;

public class Multiplication {

	public static void main(String[] args) {
		int a, b , mul;
		Scanner sc=new Scanner(System.in); 
		System.out.println("Enter the value of a:");
        a=sc.nextInt(); 
        System.out.println("Enter the value of b:");
        b=sc.nextInt(); 
        System.out.println("Enter the value of c:");
        int c = sc.nextInt();
        mul=a*b*c;
        System.out.println("Multiplication of a & b is:" +mul );
	}

}

Line-1:

package com.multiplication.java;

It is a java package , this package is created in a java project and it contains classes inside the package.

Line-3:

import java.util.Scanner;

In java, Scanner is a class. util package used for obtaining the input of the data types like int, double, float , char and strings.

Line-5:

public class Multiplication

Here ” Multiplication ” is the class-name , class is a template used to create objects & class-name first letters must be capital . It is public means we can use this package in another project.

Line-7:

public static void main(String[] args)

It is a main method in which we can execute a program.

public : It is an access modifier. The main() is public because we can access main() outside of the class , if main() can’t be public then JVM(Java Virtual Machine) can’t be called main() & code can’t be executed.

Static : static is a keyword in which the main method has to be static in which JVM can load the class into memory and call the main method without creating an instance.

Void : Void is a data type. It means no return type.

main(): Main is a function.

String [] args : string means collection of characters ,String[] args represents a collection of Strings that are separated by a space and can be typed into the program on the terminal directly.

Line-8:

int a, b , mul

Here a, b, mul is the variable and int (Integer) is a data type of the variable.

Line-9:

Scanner sc=new Scanner(System.in);

Scanner is a class and sc is the instance of the object which is the new Scanner . System.in is an argument.

Line-10:

System.out.println(“Enter the value of a:”)

System is a class name and out is the instance of the system. Println is print the new line & print the value of a.

Line-11:

a=sc.nextInt();

a is a variable that we take and sc is our instance name which is created for an object and nextInt() is a method of a Scanner object that reads in a string of digits or char and converts them into an int type.

Line-12:

System.out.println(“Enter the value of b:”);

System is a class name and out is the instance of the system. Println is print the new line & print the value of b.

Line-13:

b=sc.nextInt();

b is a variable that we take and sc is our instance name which is created for an object and nextInt() is a method of a Scanner object that reads in a string of digits or char and converts them into an int type.

Line-14:

System.out.println(“Enter the value of c:”);

System is a class name and out is the instance of the system. Println is print the new line & print the value of c.

Line-15:

int c = sc.nextInt();

c is a variable that we take and sc is our instance name which is created for an object and nextInt() is a method of a Scanner object that reads in a string of digits or char and converts them into an int type.
